A person applies a constant force  on a particle of mass m and finds that the particle moves in a circle of radius r with a uniform speed v as seen (in the plane of motion) from an inertial frame of reference
  • a)
    This is not possible.
  • b)
    There are other forces on the particle.
  • c)
    The resultant of the other forces is  towards the centre.
  • d)
    The resultant of the other forces varies in magnitude as well as in direction.
Correct answer is option 'B,D'. Can you explain this answer?

The person applies ‘F’ constantly in a fixed direction. So, to keep the particle in constant circular motion of radius ‘r’ and uniform speed ‘v’, some other force whose resultant varies in magnitude and direction also act on the particle. Since the resultant of F and other force has to have constant magnitude but varying direction, the magnitude and direction of the other force has to change from point to point on circle.

The person applies F constantly in a fixed direction. So to keep the particle in constant circular motion of radius r and uniform speed v, some other force whose resultant varies in magnitude and direction also act on the particle. Since the resultant of F and other force has to have constant magnitude  but varying direction,  the magnitude and direction of the other force has to change from point to point on circle.
